Description:
The KWA LM4 PTR GBBR is a game changer for the airsoft world. The LM4 PTR brings together two characteristics of gas blowback rifles that traditionally remain separate, affordability and reliability. The KWA LM4 PTR has taken many years to engineer and assemble and it's finally ready to come to market. The upgrade factor is something that KWA aims to address with every gun they release, because they don't want the player to have to upgrade their guns in order for them to have a good time, and that's exactly the type of mentality that built the LM4. The majority of the gun is constructed of aluminum, such as the receivers, barrel, and buffer tube, while the hand guard, pistol grip, and stock are constructed of a high grade polymer, just like a real rifle would be. The bolt movement is crisp and the recoil is very direct, and feeling that this gun gives you while being fired is unmatched by any other gas blowback M4 on the market. The construction and feel of the gun are second to none.

Another very impressive feature of the LM4, and one of the key components in making the gun operate smoothly as it does is the magazine. The magazine holds the gas to operate the gun and the 40 rounds of ammunition. The guys over at KWA have taken their years of experience constructing high quality gas pistols and magazines, and used the knowledge they've gained to engineer the LM4 PTR magazine to be as powerful, efficient, and user friendly as possible. For example, the top of the LM4 PTR Magazine is made of high impact polymer whereas the rest of the magazine is made of metal. KWA has done this for two reasons; first, the top of the magazine will be much more resistant to breaking if dropped, and second, the magazine top and feeding lip can be replaced and the magazine can be rebuilt should it become necessary. The LM4 PTR is an amazing rifle that has been engineered from the ground up to be the first and last gas blowback M4 that you will ever need to buy. All KWA guns, including the LM4 PTR, and even their magazines, are engineered to out perform.

Product Information:
Get this gun if your looking for the most realistic design, feel, kick, and everything else on the airsoft market. Why spend more than this on a gun that doesn't compare to this. This gun will not need any upgrading, the buffer tube spring is so right making the kick amazing. the bolt, forward assist, bolt catch, and all the internals work as if your holding a real AR-15. the body is metal, the internals are metal, the barrel is metal, rails are metal, and the only thing that is polymer is hand guard, stock and pistol grip

Cons:
1.) if your looking to put a RIS, the delta ring at first is reallllly hard to work with

Product Information:
KWA LM4C GBBR PTR
I got this to move away from AEGs and something more realistic and challenging for games. Mine shoots ~376 fps, and I'm lucky my local CQB field has a higher limit than usual of 350 fps so I don't have to modify anything. I also expected some wobble to it, like the fore-end, pistol grip, and stock, and there's almost none. The standard LE stock has just a little but you don't notice it when its shouldered, but the buffer tube is rock solid. The barrel doesn't move, though there's a little side to side movement of the magazine but I've yet to notice any feeding issues, and it's not something you would notice unless you go looking for it. It packs a punch as is really accurate at CQB distances. It's a really good gun that looks like it will hold up as well as anything else out there.

Pros:
Realistic operation and weight (about 6 lbs)
More kick than you'd expect (a little less than a .22 LR by the feel of it)
It's louder than you'd expect too
Trigger response is amazing
It's built really well.

Cons:
The hop up adjustment piece is as fragile as they say, so be careful with it.
Mags aren't the cheapest, but you know that going in to GBBRs I hope.
The finish can come off somewhat easily but you can buy a bottle of aluminum black at a hardware store to fix that if it matters to you.

For: KWA Full Metal LM4C PTR GBBR (M4 CQB) Airsoft Gun

Product Information:
I love this gun! I got to use it at an OP last weekend and all I can say is wow! Right out of the box this gun looks and feels great. The way it operated and felt while firing had me smiling all day long. Everyone at the field wanted to try it out. All and all the gun and magazines were worth every penny. KWA has become my favorite brand and most reliable in my opinion. If you are serious about your gear and want the best there is look no farther and CLICK the buy button NOW!

Pros:
The weight is very close to that of a real AR and the Magazines mimic the feel of a fully loaded 30 rounder. Both sights are fully adjustable and very accurate. The HOP UP is great quality and once set right this thing shoots like a laser with .25s out to 150+ feet. I can run about two full magazines before I have to refill with gas. The functional bolt is very impressive. Walking onto the field and racking back the charging handle people were staring at me like I was crazy.

Cons:
The only bad things that i have found with this gun is that it does tend to freeze up and release gas when you go full auto for a whole mag. I know it is probably not the best thing to do but I had to know what it was capable of. Also for the ones who are not used to carrying real steel this may be a bit heavy for you.

Anyone like myself who finds themselves in the realm where the airsoft and firearms communities overlap are familiar with the debate over the viability of airsoft guns for firearms training. It goes back a long time. I have used gas blowback pistols for training many years. The cost of operating an airsoft gun, although not inexpensive, is like night and day when compared to a real firearm. For that reason alone I am a proponent of using airsoft for training. It comes with limitations but it is one more tool for the tool box.

And, more recently airsoft has been gaining momentum in the firearm community as a viable training tool, especially as ammo prices have soared. Travis Haley of Haley Strategic Partners, well established in the firearm community, has endorsed airsoft guns as a means for training in a recent video and does an excellent job of explaining the advantages.

I remember getting the occasional law enforcement orders years back for gas blowback pistols because functionally they were quite similar to their real firearm counterparts but the demand was never that great for rifles and I feel one of the primary reasons was the dominance of AEGs on the market. At the time although useable for force on force training they had several shortcomings such as being dimensionally different then real firearms since they need to house a gearbox, motor, and battery. I will not detail all the shortcomings as that would take an inordinate amount of your time and mine.

Developments like the Systema PTW and others fixed some of the problems. For example, the Systema PTW used a new motor and gearbox design that aside from being more efficient enabled the PTW to have a proportionally correct size pistol grip and receiver. Also, the Systema PTW design had a functional "bolt release." I emphasize bolt release because that is what it was meant to simulate, the release of the bolt carrier group to chamber the first round after inserting a new magazine. But in reality the Systema PTW did not have a bolt at all.

That was the shortcoming of the PTW and similar systems; the lack of a bolt carrier group. As a result the charging handle and forward assist did not function. Since the release of the PTW there have been blowback AEGs but that normally consists of a thin metal plate "recoiling" back. Aside from that they are not functionally different from conventional AEGs.

Enter the gas blowback rifle. Over about the last 2 years the airsoft market has seen the emergence of gas blowback rifles. Although gas rifles have been around many years they have been outshined by AEGs but models like the King Arms gas blowback M4 and others have addressed the shortcomings of AEGs, at least in the training sense. The design of such gas blowback rifles bring airsoft guns to a new level as training tools. Like the Systema PTW they are dimensionally similar if not that same as their real firearm counterparts.

The difference comes down to the internal operation. There is not an electrical switch. When you pull the trigger a hammer is released, a bolt carrier group recoils/blowsback; into a buffer tube that has a buffer and spring. As a result the trigger feel, fieldstrip/breakdown, controls, felt recoil are all more realistic. Every sensation and operation is enhanced. The near future release of KWA's gas blowback M4, the LM4, gives me further hope for the future of the gas blowback airsoft rifle as a training tool. KWA promises it will out perform and provide greater efficiency then current platforms.

The only significant shortcomings from my perspective remaining with the gas blowback rifles is they function less efficiently in cold and no marking ability. I discount the decreased accuracy as compared to a real firearm out of hand as my primary concern as a training tool is for force on force scenarios and weapons manipulation practice. In regards to the remaining shortcomings we are light years ahead of where we were a couple years ago. I was there, I remember. The desire is always to have the perfect system but in this world nothing is perfect so for the time being such shortcomings can be worked around and should not deprive us of a viable training tool.

Will an omega 9-inch rail system (the bridged one) work with this gun? Will I have to buy a w barrel to get rid of t

I want to buy this and then add a new (at most 9-inch) bridged rail system and maybe fit a silencer underneath it, and use either my flip up magnifier with a holographic, or an illuminated scope with either my 45 degree canted iron sights or rail attachments. However I have no idea if the rail will fit, wether I will have to buy a whole new barrel to get rid of that triangle iron sight, or even how to disassemble/assemble all of it once I get it all. Any help or advice would be greatly appreciated!
